利用高分辨率的化学杂质和介电剖面资料,计算了 南极洲德龙宁毛德地(EDML)的EPICA冰芯跨越了过去16700年。的方法 用于计算格陵兰冰芯并创建2005年格陵兰冰芯年表(GICC 05) [Rasmussen等人,2006年]也被用于EDML计数。估计的最大计数 EDML计数的误差约为。5%,但初步火山匹配格陵兰冰芯记录 建议1%或更少的差异,在全新世之间的EDML计数和GICC 05。的比较 EDML和格陵兰岛的宇宙成因同位素记录也表明, 两个年度层计数年表。 参考文件: 拉斯穆森,S.

Using high resolution chemical impurity and dielectric profiling data annual layers have been counted on the EPICA ice core from Dronning Maud Land (EDML), Antarctica spanning the past 16700 years. The methodology used for counting Greenland ice cores and creating the Greenland Ice Core Chronology 2005 (GICC05) [Rasmussen et al., 2006] has also been implemented for the EDML counting. The estimated maximum counting error for the EDML counting is approx. 5%, but a preliminary volcanic matching with Greenland ice core records suggest differences of 1% or less during the Holocene between the EDML counting and GICC05. A comparison of cosmogenic isotope records from EDML and Greenland also suggests differences of less than 1% between the two annual layer counted chronologies.
